The analysis of recognition of pathogen infection and induction of hypersensitive reaction by plant receptor-type protein kinases

Plants recognize molecules derived from pathogen, elicitor, and cause hypersensitive response(HR) as one of protective reaction against pathogen. Plant cysteine-rich receptor-like kinases have been reported to relate the induction of HR, and its recognition mechanim of pathogen was analyzed in this study. A candidate for elicitor, interacted with CRK, was found in yeast homogenate, and 3-D structure of CRK was solved by X-ray crystallography and the interaction site of CRK was identified by nuclear magnetic resonance spectroscopy.
